Well a lot of people demand things of me , but most have no such authority to do so, and I just ignore them. Or there is no consequence if I ignore them. Musk is way out of line. Having been in the Air Force, and the Government and also worked for several Defense companies, the rules are very simple. You report to your manager(s).
Note that many people work on proprietary things, classified things, compartmentallized things, etc. They can NOT send out any public information over any network or email server!
Does Musk, the acknowledged cannabis user, have a security clearance or access to classified programs? Noforn, Secret, top secret, CNWDI, COMSEC, Yankee White, etc..?
